Solution 1

C#

RichTextBox rtb = new RichTextBox();
rtb.TextChanged += new EventHandler(rtb_TextChanged);

C#

private void rtb_TextChanged(object sender, EventArgs e)
{
  // process the text changed event 
}

EDIT

Ok, without knowing what kind of richtextbox i'll try to answer.
Assume you have created object of richtextbox from code behind and its name is rtb

if you type rtb and dot you can find the methods properties and events of it, find TextChanged and hit enter.
ones you done that press + mark and = key and press tab key twice. it will generate event for you.

hope this helps.

How do you know which RichTextBox? OP did not specify its type (there are more than one), and you support this. We should avoid answering those ambiguous questions.

Way of adding event to a control is common in .net so answer was helpful that's why OP accept it. agreed with you but guessing and answering is sometimes better than clarify by a comment.

Well, I guess it depends on personal preferences to some extent... well, as you did not miss anyway, I'll up-vote it this time, only by 4, not by 5. I'll explain where is the imperfection: rtb_TextChanged violates (good) Microsoft naming conventions. Yes, auto-generated code does violate Microsoft naming conventions, and this is even good -- it tells you that you did not retouch this code yet and reminds you to rename the member to something semantic when you get to it. Also, I would advise anonymous handlers in some 99% cases (and not using Designer on event; the Designer writes bad handler code).
